The great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. The figure illustrates this for five galaxies lying along a straight line, with the Milky Way Galaxy at the center. B) Using the data from the figure, calculate the velocity of galaxy 3 relative to galaxy 2 in km/s. C) Using the data from the figure, calculate the velocity of galaxy 4 relative to galaxy 2 in km/s. D) Using the data from the figure, calculate the velocity of galaxy 5 relative to galaxy 2 in km/s. E) Using the data from the figure, calculate the velocity of galaxy 1 relative to galaxy 5 in km/s.
